2024-01-03(水) 冬休みの [長年日記]

_ 宿題

写真アルバムの自動生成。

長男氏とNASに置いてる写真の共有方法を考えたのは良いが、apacheの自動インデックスだとサムネとか見えないので困る。

と言うことでhtmlのインデックス自動生成ツールを作っていたのだけど、ようやく完了。

とりあえず生成するだけのものは数日で出来て、長男には公開してた。

でも、ファイル追加したら自動で生成とか重複起動防止とか、体裁をちゃんとするのは冬休みの宿題だったのだ。

ちなみに、表示ファイルのサムネを作っているのではなくて縮小表示で並べてるだけなので表示時間は掛かる。

いわゆる手抜きである(ﾟ∀ﾟ)
